STEAM-GENERATOR FOR HYDROCARBON-BURNERS- SPECIFICATION forming part ofLetters Patent No; 758,807, dated May 3, 1904:.

Application filed December 9, 1902. lerial No. 134,481.

To Ml w/wm it may concern.-

Be it known that I, GEORGE W. ARPER, a citizen of the United States,residing at Oakland, county of Alameda, State of California, haveinvented certain new and useful Improvements in Steam-Generators forHydrocarbon-Burners; and I do hereby declare the following to be a full,clear, and exact description of the same.

The present invention relates to an improved construction ofsteam-generators for hydrocarbon-burners whereby the supply of waterinto the generating-cylinder is automatically controlled by the pressureof the generated steam, the connection of the outlet-pipe for thegenerated steam with the steam-generating cylinder being such as toprovide against sediment within the cylinder entering therein andclogging the discharge-nozzle.

To comprehend the invention, reference should be had to the accompanyingsheet of drawings, wherein Figure 1 is a perspective view illustratingthe generator and the hydrocarbon-burner applied to an ordinary cookingstove or range, and Fig. 2 is a longitudinal sectional view of thegenerator and burner removed from the stove or range.

The numeral 1 is used to indicate an ordinary cooking range or stove,and 2 the heating-chamber thereof. \Vithin the said chamber is arrangedthe tire-pot 3, into which oil is delivered from the supply-pipe 4:. Thetirepot 3 is formed with an oil-seat 5, into which the oil deliveredfrom end 6 of the supplypipe 4 is received. Above the discharge end 6 ofthe supply-pipe is arranged a deflecting disk or plate 7, which issupported a slight distance above the discharge end 6 by the downwardextensions 8. The supply of oil or hydrocarbon through the supply-pipe Lis regulated by the controlling-valve 9.

Through the wall 10 of the range or stove 1 extends the steam-generatingcylinder 11, which projects into the heating-chamber 2 above thefire-pot 3. The outer end of the cylinder 11 is provided with a plug 12,which screws therein. The removal of this plug permits of the insertionof a tool into the cylinder for the purpose of cleaning same.

(No model.)

To the cylinder 11 outside of the stove or range connects thewater-supply pipe 13, the supply of water therethrough into the cylinderbeing regulated by the controlling-valve 14.

From the inner end portion of the steamcylinder at its top extends theoutlet-pipe 15 for the generated steam. This pipe extends through thewall 16 of the stove or range and then returns to the heating-chamber, acontrolling-valve 17 being interposed within the outside section of thepipe. To the free end of said pipe is attached a discharge-nozzle 18,which is arranged to deliver a jet of steam onto the deflecting orspreader plate or disk 7.

To prevent heavy sediment of the Water delivered into thesteam-generating cylinder, which sediment moves over the wall of thecylinder, being carried into the steam-outlet pipe and clogging thejet-nozzle thereof, the receiving end 19 of said pipe extends into thecylinder 11 a short distance below the upper surface thereof.

In case the water fed into the cylinder 11 fills the same prior togeneration of steam, and thereby causes water to be delivered into thefire-pot through the discharge-nozzle 18, it is only required that thecontrolling-valve 17 be closed. When thus closed, the pressure of thesteam as generated will overcome that of the water-pressure andgradually force the Water back into the supply-pipe. After thegeneration of steam within the cylinder 11.

the pressure thereof will regulate the feed of water into the cylinderin proportion to the consumption thereof by being discharged into thefire-pot. The supply of water into the steam-cylinder may thus be saidto be automatically controlled by the pressure of the generated steamtherein.

By the foregoing-constructed steam-generator the arrangement of theoutlet-pipe for the steam is such as to prevent the water-sediment beingdelivered to the discharge-nozzle, while at the same time an excess ofwater feed into the cylinder 11 is obviated by reason of thecounter-pressure of the generated steam.

The steam as ejected from the dischargenozzle strikes against the diskor plate 7 and is broken up and deflected into the flame of burninghydrocarbon within the fire-pot, the

heat from which bears against the steam-gen positely-disposed members,the communicating ends of Which extending Without the heating-chamber, aregulating-valve in said extended portion, one of saidoppositely-disposed members passing through the top of the cylinder to apoint beyond the inner surface thereof, and the other member terminatingin a nozzle.

In Witness whereof I have hereunto set my hand.
